TECHNICAL FIELD

The present invention relates to a cap for a container, and more particularly to a cap provided with a push type opener, in which a sealing member is detached from an entrance of a container or the cap.

BACKGROUND ART

FIG. 1 is a cross-sectional view of a cap, provided with a conventional opening structure, for a beverage container.

The cap provided with the conventional opening structure comprises a cap main body 3 detachably connected to an entrance of a container 1 sealed by a sealing member 2, an elevating member 4 installed at the external surface of an upper portion of the cap main body 3 such that the elevating member 4 can move up and down, and a subsidiary cap 5 covering the upper portion of the cap main body 3.

When a user wants to drink the beverage contained in the container 1 provided with the cap, the cap main body 3 is detached from the container 1, and the sealing member 2 is removed from the entrance of the container 1. Then, the cap main body 3 is attached to the entrance of the container 1, and the subsidiary lid 5 is opened and the elevating member is pulled upwards by a user's hand. Thereby, an upper portion 4′ of the elevating member 4 is separated from a head portion 3′ of the cap main body 3, thus opening the entrance of the container 1 and allowing the user to drink the beverage exhausted from the tilted container 1.

In case that the user does not want to drink beverage contained in the container 1, the user presses the elevating member 4 by hand so that the elevating member 4 is returned to its earlier position, thus closing the entrance of the container 1.

Since, in order to open the cap provided with the conventional opening structure from the container 1, the cap main body 3 is detached from the container, the sealing member 2 is removed from the entrance of the container 1, and then the cap main body 3 is attached again to the container 1, it causes inconvenience to users.

Particularly, since the sealing member 2 is firmly attached to the entrance of the container 1 for sealing the container 1, it is not easy to detach the sealing member 2 from the container 1. Further, since most of the conventional sealing members 2 are detached from the container 1 by means of the user's hands, the entrance of the container 1 is contaminated by the user's hands when the sealing member 2 is detached from the container 1, thus causing unsanitary conditions to the beverage contained in the container 1.

It is difficult to store additional contents separately from the contents contained in the container 1 provided with the above-described conventional cap, thus causing the container 1 to require an additional container or the cap to have a complicated structure.

When a user wants to drink the beverage contained in the container 1 provided with the above-described conventional cap, the elevating member 4 is pulled upwards so that the cap is opened from the entrance of the container 1, and after the user drinks the beverage contained in the container 1, the elevating member 4 is pushed into its earlier position by the user's hands, thus contaminating the entrance of the container 1 and causing poor sanitary conditions.
